Show HN: Arrow. Point your phone, walk where it says, find out where

Awesome. Hey, a sentence worth of privacy policy if a whole thing would be too much would make me feel better about given precise location. Definitely curious to try it though. Need to get it over a credibility hump though, I suppose. Which I hope is received as an honest opinion on the general state of software this year, because I don't have any specific concern about Arrow. :)

Fun idea. Before I try it, how far should I expect to go before reaching my destination?
